Use of inulin and inulin derivatives

#This invention relates generally to the field of skin cosmetics and more particularly to the use of inulins or inulin derivatives for a number of applications in the treatment and care of human skin.

#Modern skin treatment preparations are expected to satisfy stringent consumer demands with increasing emphasis on their skin care and preventive qualities. Thus, the preparations are expected, for example, to provide protection against drying out, ageing and wrinkling, to strengthen the immune defense, to prevent lesions, i.e. to have an anti-inflammatory effect, and to leave the skin with a pleasant feel. Accordingly, the manufacture of such products involves the problem of adding to the preparations a number of active ingredients which, together, develop the required performance profile without interfering with one another or even giving rise to unwanted side effects. Accordingly, there is a particular interest in active ingredients which combine the required properties and especially in those which are of vegetable origin.

#Accordingly, the problem addressed by the present invention was to provide such active ingredients.
